為建立橫山梨苗快速繁殖系統，以縮短成苗時間，於1996年至1997年間進行溫度及局部加溫對橫山梨枝條接插成活之效應試驗，結果顯示30/25˚C環境之插穗初期萌芽率高，但澱粉及總醣量迅速下降而導致成活率低，在15/13˚C溫度環境下，接插成活率砧木為73.3%，插穗部分為80.0%，而在30/25˚C環境下，分別降低為20.0%及33.0%，此外砧木基部加溫亦獲得較高之接插成活率。
The effects of temperature and heating treatments on the survival of sand pear graft-cuttings were studied in three trials in 1996-1997. Results showed that the rootstock and scion survivals were 73.3% and 80%, respectively, under a day/night cycle of 15/13˚C, but was reduced to 20% and 33.3% under 30/25˚C condition. Although buds of shoot bursted earlier under a 30/25˚C region, however, a decrease of survivals of cuttings by rapid decline of starch and total carbohydrate of shoot was observed. In addition, heating on the basal of rootstock also increased the survivals of graft-cutting.
